An Investigation of the Channel Crosstalk in Optical Heterodyne Controlled Phased Array Radars.
Abstract
The principal objective of this project is to investigate problems associated with achieving the drive/read-out system complexity necessary to control a phased array antenna with optical heterodyne techniques. In particular, this work has concentrated on multi-channel microwave optical conversion. The approach has been to study the problems associated with device arrays of single sideband modulators that would be necessary to control the amplitudes and phases of all signals delivered to a phased array front end. The incorporation of our available in-house developed tools into that of already existing tools (such as MDS-Microwave Design Software) has been undertaken to design a single side-band modulator (SSBM). It was found that MESFET oscillators and the associated control lasers can be modeled by simply changing a constant in the model to give their characteristics with and with out optical injection. This is useful for injection locking of active antennas for accurate and efficient phased array antenna design. (AN)
